[Child tuberculosis at the teaching hospital of Brazzaville from 1995 to 2003].
In the paediatric service of the teaching hospital of Brazzaville, 582 files of children hospitalized were studied from January 1995 to December 2003. To determine tuberculosis frequency among sickle cell children and estimate the clinical and paraclinical aspects, a case-control study of tubercular patients with HIV negative serology was carried out by comparing at the same time a cohort of 75 sickle cell patients versus 125 patients without sickle cell disease. The results of these studies are as follows. The main assessment is the high frequency of tuberculosis. In 1995 the tuberculosis rate reaches 8%, in 2003 it was up to 13.6%, and 20.6% in 2000 due to the serious consequences of the recurrent wars between 1993 and 1999. Another cause of that high frequency is the rate of HIV/aids patients with a frequency of 2.5% of hospitalization ranging from 1.6 to 3.2%, among them 35% of the tubercular patients were seropositive. The tuberculosis prevalence was 7.4% among sickle cell patients versus 14.2% among control patients. Infection was more often identified in control patients (51.2%) than in sickle cell patients (24%). 68% of the parents were really poor and 18.5% of the children were evicted from their home by war. The pulmonary localizations were prevailing in groups of patients with sickle cell disease as well as in group of control patients. Pleuritis was observed in 8% of the patients with sickle cell disease versus 16.8% for control patients (P = 0.02). No patient with sickle cell disease had a miliary. Anergia to tuberculin test was reported in 35.8% sickle cell patients versus 10.4% for the control patients (P = 0.001). Tuberculosis prevalence is higher among control patients than in sickle cell patients. The high proportion of clinical and paraclinical data of tuberculosis did not significantly differ from the two groups. Evolution was good for 98% of the patients, 1.4% of them died; 74% of deceased patients were affected by HIV/aids.
